I am not sure this is sensible at all, after all these years. I suspect that it is much more productive to deprecate and remove "@" that is a built-in synomym for HEAD (but "refs/remotes/origin/@" does not act as a synonym for "refs/remotes/origin/HEAD"). Having two ways to call the same thing merely adds to confusion in this case, unlike "HEAD" referring to 'master' (when 'master' is checked out), which is also to have two ways to call the same thing, but adds a true convenience. Those who really want to use @ can do something like $ echo "ref: HEAD" >.git/@ or something, perhaps.
